大气辐射交换对海风模拟结果的影响

INFLUENCE OF RADIATION EXCHANGE ON SEAWIND SIMULATION RESULT

建立一个二维的中尺度静力模式,考虑太阳短波辐射、长波辐射、大气中水汽、地表面粗糙度、反射率和土壤层温度等物理因子,讨论大气辐射交换对海风结构的影响,发现如果忽略辐射因素,海风只能局限在较小的范围内,不能向内陆纵深发展。

A two dimesional static model is developed in the present paper,taking into account the physical processes such as the solar longwave and shortwave radiations,moisture of air,roughness of the earth-surface,albedo,temperature of the soil layers. Some effects of the longwave and shortwave radiations on seawind are discussed by using this model. It is found that if the radiations are neglected,seawind will be confined to only a small space without reaching further into the inland.
